Product Questions & Answers

Q:Where is this part located on 2018 Kia forte?
Lisa C.
A:BEST ANSWERHi Lisa, I'm glad to assist you. This is not compatible. We don't have a direct-fit fuel pressure regulator available for a 2018 Forte. We suggest checking the local part stores around your area or the Kia dealership directly on what they have available to offer you. I hope this helps, and we thank you for inquiring. Show less
